If you happen to be wandering about Madison Avenue on Saturday be sure to stop by the Ivanka Trump Fine Jewelry boutique to learn about the 4C's of buying a diamond and enjoy the forgotten 5th C, champagne! Every Saturday the store will have certified gemologists on hand plus complimentary champagne will be given out to customers. Also, every client visiting the store will received a $100 gift card towards any purchase. Prices of pieces in the store start at $800. Happy shopping! —Cari Wolfert
